Wheels ''Shaking'' -> RESOLUTION in posts #22 & #30 - Page 2

THATS AWESOME INFO. He's an interesting theory, I believe the car was hit before because of the paint on the car and the freaking front bumper is not flush at all. Driving the car it doesnt feel that bad only when braking and of course the vibration around 60mph other that that the car is fine. Just wanted to point that out. Oh and the vsa light stays on but thats probably a sensor.

well... then, maybe there are some more serious susp./axles problems, aftermath of the collision, but I'd still start by following the list in my previous post.

ok guys i have been experiencing this issue as well, and i have been thinking about posting it for a few months but i haven't. I consider myself fairly experienced/knowledgable, and here is usually where i come first to help if i can when i log on. So here is my dealing with this issue and ideas.

Ok, I am going to describe my issue in detail even though i am 99% sure you are experiencing the exact same thing. Upon acceleration in any gear, the car starts to shudder at 60 then stops around 68 or so. It does not shudder under deceleration. Note: my car did not do this when i bought it, and it has progressively gotten worse and worse. it began as only slight vibration at 60 and has progressed to very noticeable shudder that starts at 60 peaks at about 63~ and tapers off until its gone about 68. This has taken approximately 3 months.

I am owner number 2 of my 04. The first owner said the only collision that happened ended in a bumper replacement, that was performed by Acura. Car tracks perfectly straight. So collision is not the issue. I have had warped rotors before, and it is only doing it under acceleration not deceleration or braking. My rotors on my TSX are not warped, so they dont have anything to do with it. I have had bad wheel bearings before, there is no metal on metal squeaking, and that would shudder at a constant speed not under accel, decel, braking or turning. I have stock wheels. So it isnt the center ring thing. I have not touched the wheels nor hit anything major that would dislodge a weight on the wheel. However i have not checked the balance. But i have had this issue before as well. It has been my experience that this would cause a big vibration at low speed and taper off as speed increases because the centrifugal force of the wheel will eventually balance it out enough for the suspension to absorb all or most of the vibration and you wont feel it. I don't think it is flat spots in the tire, because we have abs, i haven't engaged abs, i dont have uneven tire wear, and i rotate my wheels anyway. Not to mention i drive spirited enough that the turns would take care of my uneven tire wear if i did have any. Do not think it is transmission related because i would think it would do this at a certain rpm level in each gear. I have no CELs or Sensor lights (ABS, VSA, etc.).

Ok (i already see this is a long one i apologize), Axles... potentially yes, as it makes sense since they are behind the output shaft of the transmission so they will be rotating at a speed relative to the speed of the car, so that makes sense. but how? Granted I do drive very spirited several times a week, to include catching second, third, and sometimes fourth (on a good day LOL). But, I just don't see a stock clutch clamping enough torque to bend/warp/unbalance the axles... thoughts please?

EDIT: when i drive in a spirited manner, i do not launch from a dig. I roll into first then get on it.

true, a long read, but a good summary. Based on all you said I do believe it's wheel balancing you have a problem with. If there was a previous owner there, even though all looks ok, you never know exactly what happened in the past.
This sounds like a typical case of unbalanced wheel(s). Depending on the degree of deficiency, you may experience shaking at different speed, but minor deficiency is usually apparent between 50-70 mph, so you're right in that range. Start there, and let us know what happens.

wilsonader · 03-20-2009, 11:56 AM

im guessing you needa get the wheel balanced

Peregrine · 03-20-2009, 12:20 PM

so musicman, H22A, were you guys able to fix anything yet? Just curious...

poopydik · 03-24-2009, 01:45 PM

nope its not the wheels please learn from my mistake last month....I had the same problem between 55 and 63MPH my car would shake pretty bad, at first i thought it was the rotors so i did replace them and the pads, didnt fix it then i got my aftermarket rims re balanced and still had the problem so i finally brought the car into the dealer....It was the axles and the gears that were burn out...they changed it under extended warranty but if I didnt have the coverage it would have cost est. $750 but havent had the problem since....

The technician said it was because of my rims/low pro tire/offset/and drop that cause extreme pressure on the axle causing it to bow in the wrong direction that caused the gears to burn out resulting in shaking.....

If I were u I would go straight to the Axle and if not at least get the diagnostic before u waste money on rotors/balancing....

Did you have the axels replaced on both sides?
I am experiencing some vibrations. When I first drive the car in the morning it vibrates a little for a couple of minutes (I know it's strange), but than it goes away. It does vibrate a little when I am braking lightly, but when I brake hard at high speed it vibrates quite a bit.
I am still thinking it's the rotors, as it never did that before.

Peregrine · 03-24-2009, 06:54 PM

vibration while braking is definitely associated with warped rotors, but poopy's feedback is very interesting. I'm not sure how bad axles would act under braking. The final decision is up to you, but ultimately you may want to take that car to a shop for an inspection.

poopydik · 03-24-2009, 07:02 PM

^^^^ the cheapest and fastest way to the problem is diagnostic, most places will do it free dont go the long hard route i went!!!

I did have the axles replaced on both sides....the vibrating your experiencing does sound like what peregrine states because the rotors are stil cold, with heat the vibrating goes away...the fact that it goes away confuses btu i know that with the axles it does not go away, not matter what RPM or time of day between 55-63MPH that sucker was shaking....just get a diagnostic bro, ask your dealer most will do it free if ur an on going customer.....

GOOD LUCK

musicman3636 · 04-02-2009, 12:38 AM

still havent replaced anything yet because of lack of money but I will let you guys know

HK12 · 04-21-2009, 08:36 PM

Hello all, new tsxer.Just got my 2004 TSX 2 weeks ago. And i believe i have the same problem with the vibration.Mine is a little weird though the vibration with me starts when I accelerate only from 20-30 and 50-60 when I go above 30 and then 60 it disappears.I though it was the weels and tire balancing but it wasn't.Just checked all the tires and we balanced them perfectly but vibratrion continues.Went to my mechanic and they can't seem to know what the problem is but they were guessing axels.Will have them replaced by end of the week and see what happens,will let you know.Anyone with other experience please let me know...

"Axles and the gears"?? what gears?

The explanation the tech gave you is bullshit. I could maybe see that being probable if you had some 22's or something but anything a 19 or under isnt going to make a difference. Unless you have some depleted uranium wheels or something. Think about it. Our car comes stock with 17's that weigh like 24lbs. (guessing i dont remember exactly). and the tires that come on them arent exactly "high" profile. IMO I think this is a manufacturer's defect in the axles. /2 cents

I will swap them out one day... been lazy alot lately and just got back on my feet from a leg surgery. Got some mufflers put on today to go witht he rest of my exhaust mods...

It sounds so good. Alot deeper tone than i was expecting. and it is pretty friggin loud too. I will put up a sound clip on my old exhaust thread soon.

HK12 · 05-03-2009, 02:09 PM

Ok as promised an update on my progress. It took a while to find the axles and to be delivered but finaly everything is done and it's true the shaking when accelerating is from the axels.Changed the front two and the car runs perfectly my mechanic charged $430 for the parts and labor.
